IMPROVEMENT lN HILLSIDE-FLOWS.

Specification forming part of Letters Patent No. 6,553, dated June '26,1849.

To all whom it may concern:

Be it known that I, DANIEL ROBE, of Springfield, in the county ofSangamon, State of Illinois, have invented a new and useful Mode ofConstructing a Plow, which in its improved form is called RobbsRevolving OaryPlow and .do hereby declare that the following is a fulland accurate description thereof.

It is in general shape and form that of the Cary plow; but what I claimas my invention is the extension of the mold-board of the Cary plow byadding a triangular piece on the up per side and so arranging it thatthe moldboard shall revolve in such a manner that either the upper orthe lower edge may operate as a share, and by fastening it permanentlyto a triangular landside, as in Figure 3 in accompanying drawings. Toenable it to revolve, an iron rod, A B, extends from the heel ofthc plowthrough one of the corners of the landside to the center of that side towhich the mold-board isnttached. When used the moldboard is secured in afirm position by the iron rod 0 D, which extends from one side of thelandside to the vicinity of the round, to which the handles areattached, so as to be conveniently reached by the operator. When it isdesired to reverse the mold-board so as to enable the upper edge tooperate as the share, the rodOD may be drawn toward the operator, whenthe mold-board, with the landside at tached, will immediately revolveupon the iron rod A B, after which it may besccured by replacing theiron rod 0 D in its former position.

The mold-board is designed to be constructed of wrought-iron, in twopieces equal in size and shape, the joint being designated by the line BE in the accompanying drawings.

The landside will be made of cast-iron and secured to the mold-board byscrew-bolts.

The extension of the mold-board is designated by the letters I J K inthe accompany ing drawings.

I repeat that I claim as my invention--,

1. The extension of the mold-board as above described, and thearrangement of the moldboard so as to make it and the landside revolvetogether and enable either the upper or lower edge to act as a share andto throw the soil upon either side of the plowman.

2. In combination with the above, the arrangement of the iron rod 0 Dand the iron bar L M and its arm G H, so as to secure the mold-board ina firm position when used.

3. The constructing of a three-sided landside which is not fastenedpermanently to the woodwork, but acts independently thereof, as hereinspecified and represented.

DANIEL ROBE.
